I haven't read this whole thread but from what I know about ebay, once a person bids or does a 'buy it now" (yes you can sell things straight out instead of auctioning) you are in a legal, binding contract to sell to the person weather or not you like them or think they will provide a good home or not. In that case, no, no good breeder would get themselves into a contract to sell to someone that they have not interviewed.
